之。此等研究之結果即為本致動機構之配置。 20 因此，通常此等致動機構包含大量零件，更精確來說， 超過20種零件被用來建立該機構。在本配置中，該機構只 包含12種零件’這可大幅簡化其製造並進而降低其成本。 一般而言，引擎的電力連接需要焊接以及若干配置以 使總成可以配合不同車款之連接可能性。根據本配置，電 1311960 動引擎之最大部位的尺寸被設置成與車體及外殼蓋成直 角，藉此配置，該引擎之連接端部位於該致動總成外殼之 側面部位，使連線可以透過接合(刺穿）完成；此等衍生自該 外殼之連線數量足以使其根據接收車款的電路來接納各種 5 不同的連接方式。 根據一般的構造，該齒輪内側之彈性夾展現一以若干 片段建立成的環狀組態，並由起初被隔離之彈簀壓靠至該 致動栓，該彈簧沿該夾四周被設置於外側。此構造可以滿 足需求，但相對複雜且會使生產線之總成安裝複雜化。為 10 了克服此一問題，在本配置中，雙邊且彈性之環狀結構被 提出。此一構造比傳統更簡單且可簡化生產線之安裝。 根據傳統構造，將該外殼之一部分固定至另一部分的 構件主要包括框邊，該框邊具有以關節方式被併入該外殼 之零件之一的車窗，以及被併入另一零件之對應保險桿， 15 且各該關節框邊之車窗與其耦合。此一構造方法相對複雜 且需要同樣相對複雜的模造工具。此外，該框邊在若干次

machine that can provide better use and manufacturing conditions. t prior art] The conventional external mirror actuating mechanism mainly comprises: a pair of electric micro-engines. The electric micro-engine has an endless shaft coaxial with its geometric axis and is arranged relative to the rear view mirror to make the rear view mirror Moving along its horizontal and vertical geometric axes; 10 - a ring gear coupled to each of the endless shafts; two spring clips incorporated into the gear; two thread actuating bolts that pass through and are coupled to the The sleeve can be axially moved, covering the outer casing of the engine and the gear assembly, and the end of the actuating bolt protrudes toward the outer casing and is placed on the inner surface of the rear wall of the cover of the outer rear view mirror assembly; An intermediate joint assembly, the first portion of which is incorporated into the outer casing; 15 a support frame support, the rear portion of which includes a pair of grooves, the end of the actuating bolt being coupled to the groove through the joint, and the support bracket The plate further includes a second portion of the intermediate joint assembly. Although this actuator is in line with its purpose, research continues to improve. The results of these studies are the configuration of the actuation agency. 20 Therefore, usually these actuating mechanisms contain a large number of parts, and more precisely, more than 20 parts are used to build the mechanism. In this configuration, the mechanism contains only 12 parts' which greatly simplifies its manufacture and thus reduces its cost. In general, the power connection of the engine requires soldering and several configurations to allow the assembly to accommodate the connection possibilities of different models. According to the present configuration, the largest portion of the electric engine 1311960 is sized to be at right angles to the vehicle body and the outer casing cover, whereby the connecting end of the engine is located at the side of the outer casing of the actuating assembly, so that the connection can be This is done by splicing (piercing); the number of wires derived from the casing is sufficient to accommodate a variety of different connections depending on the circuit receiving the vehicle. According to a typical configuration, the elastic clip on the inside of the gear exhibits an annular configuration formed by a plurality of segments, and is pressed against the actuating bolt by an initially isolated magazine, the spring being placed outside the clip . This configuration can meet the requirements, but is relatively complex and complicates the assembly of the production line. To overcome this problem, in this configuration, a bilateral and elastic ring structure is proposed. This configuration is simpler than conventional and simplifies the installation of the production line. According to conventional construction, the member that secures one portion of the outer casing to the other portion primarily includes a frame edge having a window that is one of the parts that are jointly incorporated into the outer casing, and a corresponding portion that is incorporated into another The bumper, 15 and the window of each joint frame are coupled thereto. This construction method is relatively complex and requires the same relatively complex molding tools. In addition, the frame edge may break or lose its effect after several opening and closing operations, which may jeopardize the assembly's latch. In order to overcome this disadvantage, the connection of the outer casing parts of the present configuration is completed by an opening in which a portion 20 is placed in one portion and a separating bolt disposed in the other portion. The openings and the latch have a geometry to couple and decouple It can be achieved without causing damage to the site. However, such openings and pegs can be formed from relatively simple mold details without the need for drawers and other complicated structures. According to an implementation possibility, the middle 1311960 joint of the mirror bracket in the outer casing provides a balance beam, wherein the intermediate point is jointed to the outer casing and the end thereof supports an articulated rear view mirror pallet. The design provides a similar universal joint operation. According to the conventional construction, mounting the balance beam to the outer casing, in particular, mounting the pallet to the balance beam is a rather complicated operation, which can complicate production. In order to overcome these disadvantages, the means for coupling the pallet to the balance beam comprises the pallet provided with a central circular opening, wherein the balance beam is configured and imparts two C-shaped grooves of opposite diameters and turning in opposite directions The respective ends of the balance beam are joined thereto. The configuration of the groove allows the end of the balance beam to be placed in front of the groove opening, and the coupling 10 action can be simply accomplished by angularly moving the balance beam along its transverse axis. The improved structural detail of the actuating mechanism can be used as a basis for a mechanism that is much simpler to construct and install than conventional mechanisms.

According to the above main construction, the actuating mechanism of the present invention can be used to change the material, size, construction details and/or functional configuration of the cover, as long as it does not violate the claimed protection range. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the actuating mechanism in which the parts are separated and shown in perspective, 12 1311960 Figure 2 shows the frame from which the actuating mechanism is mounted. For the plane view of the pallet, 3⁄4, sample, Figure 3 shows the SS section shown in Figure 2; Figure 4 shows the enlarged detail of Figure 3; 5 Figure 5 shows the TT shown in Figure 2 Section 6; Figure 6 shows the XX section shown in Figure 2; Figure 7 shows the YY section shown in Figure 6; Figure 8 shows a fragment of the gear; Figure 9 shows the plane The frame holder; 10 Figure 10 shows the LL section shown in Figure 9; Figure 11 shows a diameter segment of the housing body; and Figure 12 also shows a diameter segment of the housing cover.
